host-zin only builds the 'zic' program, which pacakge can access using
$(ZIC), so host-zip (our package) does not need the tz-data itslef.

But postgresql needs the time zone info. It can use either the system
ones, or it has a limited set bundled in its source tree, in:
    postgresql-9.3.3/src/timezone/data/

That's what the error message hints at:

    When cross-compiling, either use the option --with-system-tzdata to use
    existing time-zone data, or set the environment variable ZIC to a zic
    program to use during the build.

Yann E. MORIN.
